The double helix is in the shape of the DNA molecule, discovered by biologists Watson and Crick in March 1953. Fashioned from spring steel & then silver-plated, this bracelet is available in small (5½ in = 140 mm) and medium sizes (6¼ in = 159 mm).

The bracelet is much nicer than the photo indicates. Its spring has just the right amount of flex, making this bracelet a joy to wear.
